    The sum of the exterior angles of all polygon is always equal to 360°. The exterior angle sharing the same side with that of the right angle of the triangle is equal to 90°. If the other exterior angles are 13x and 14x then, they add up to 270°.

    The equation that would allow us to determine the values of the angles are,

    13x + 14x = 270

    x = 10

    The exterior angles are 130 and 140°. The exterior angle and the interior angle always add up to 180°.

    Interior angle 1: 180° - 130° = 50°

    Interior angle 2: 180° - 140° = 40°

    Therefore, the measures of the two acute angles of the triangle are 50° and 40°.
